Mechanical Behaviour of TiO₂ and Graphene Nanoplatelets Reinforced ZE42 Magnesium Alloy Hybrid Composites: A Short Review

These key attributes including high specific strength, low density and good manufacturability properties make magnesium alloys (e.g. ZE42 (Mg–Zn–Zr)) appealing as high performance materials for applications in the aerospace and automotive industry directed towards lightweight structures. Consequently, TiO₂ nanoparticles & Graphene Nanoplatelets (GNP) have been widely incorporated as hybrid reinforcement within metal alloys to improve their mechanical properties through the mechanism of grain refinement, and load transfer mechanisms. The review provides a short overview of the new investigations carried out on TiO₂ and GNP reinforced with ZE42 Mg composites by covering all aspects associated with fabrication methods, microstructural development, strengthening mechanisms, mechanical performance as well as knowledge gaps for further research.
